APPARATUS FOR SPINNING AND DOUBLING COTTON, 84.0

SPECIFICATION forming part of Letters Patent No. 620,825, dated March 7,1899. Application filed November 8,1898- S rlel ITO- 695,807- (Nomodel.)

To all whom it may concern:

Be it known that I, THOMAS ASHWORTH, a subject of the Queen of GreatBritain, residing at Urmston, near Manchester, in the county ofLancaster, England,have invented new and useful Improvements in orRelating to Apparatus for Spinning and Doubling Cotton or other FibrousSubstances, of which the following is a specification.

This invention relates to apparatus for the formation of cops of yarnupon bare spindles, (or upon paper or other tubes fitted thereon and itconsists of certain improved apparatus for applying a graduated ordifferential drag or braketo the spindles, so as to equalize the pull ofthe yarn upon the said spindles. The improvements are illustrated bythree sheets of drawings hereunto annexed and will be readily understoodon reference thereto and by the following explanation thereof.

Figure 1 on Sheet '1 of the drawings is a side elevation, partly insection, of so much of a spinning-frame as is necessary to illustrate mypresent improvements, and on Sheet 2 Fig. 2 is an enlarged elevation,and Fig.

. 3 a plan View, of the improved drag or brake apparatus detached. Fig.4, Sheet 3, illustrates a modification of the same, hereinafter moreparticularly described.

On Fig. 1, a is the spindle-rail, and b the lifting-rail, c the spindle,and d the tubular cup-shaped flier. At the back of the spindle rail a Imount a shaft 6, which I furnish at intervals with arms or levers g, andto this I give a rocking motion at the required speed by any suitablemeans, and to the bolster h, which supports the spindle 0, (see Figs. 2and 3,) I fix on either side a pin or screw i, diametrically opposite toeach other. These pins or screws serve as pivots, upon which I hang alight wire frame 70, on which is fixed a tuft or roll of cotton or othersuitable material Z, which bears against the spindle c, passing throughthe bolster h, a small quantity of oil or other lubricant beingpreferably applied to this material on the frame.

The arms g, fixed upon the shaft e, carry longitudinal wires m, (seeFigs. 2 and 3,)

and above these wires are arranged a series of light wire leversm n hungon the pivots 'i and carried by the horizontal arm la which forms partof the brake-frame before mentioned, and as the rocking shaft eoscillates the levers 9 cause the wires m to recede from the levers nand wa which by their weight act on the brake-frames k and cause thetufts or rolls Z to act as a brake against the side of the spindle.

The levers may be made in a single form,

as shown on Fig. 4, Sheet 3, in which case a single wire n, resting onthe arm of the brake, may be used; but I prefer to use the compoundlevers shown at Figs. 2 and 3, as the brake is applied to the spindle ina more efficacious manner, the drag being more evenly and graduallyapplied.

In the single form, Fig. 4, the wire at is made with a single loop, andto this is hooked one end of a chain 0, which is allowed to hang down ina loop, its other end being attached to a stud or screw 19 upon a shaftor bar q above. The weight of this chain 0 acting upon the lightbrake-frame it causes the tuft or roll of fibrous material Z to put amore or less strong drag upon the side of the spindle.

In the compound arrangement shown at Figs. 2 and 3 the wire W is hung ona loop 1 of the wire 01. and passes through a second loop 2. Thus theweight of the chain hangs principally upon the loop 2 of the wire levern and exerts its full weight upon the brakeframe is; but but when thelever n is raised up by the wire m the weight hangs upon the loop1,'which, being nearer to the pivot of the wire lever it, gives adiminished pressure to the brake. If the wire m rises still further, itwill lift both the wire levers n and n and take off the drag altogether.be regulated as required to suit different counts of yarn by turning theupper shaft or bar q around by hand, so as'to wind or unwind the chain 0onto or from it, thus shortening or lengthening the hanging portion andof course correspondingly altering the weight and the amount of dragupon the spindle.

As before mentioned, the rocking motion given to the shaft 6 is soregulated that the greatest drag is applied to the spindles at themoment when the yarn is being wound upon thelargest diameter of the copandis gradually lessened or withdrawn as it reaches the This drag maysmallest diameter thereof, so that the amount of drag is alwaysproportioned to the pull of the yarn upon the spindles.

I claim as my invention 1. The combination with a series of spindles andloose hanging brake-frames of a series of light wire levers acting uponsuch frames and a series of chains, connected at one end with suchlevers, falling into a festoon or loop, and with means at the other endfor regulating the lengths of such loops, and with means for raising andlowering such levers to take the weight of such loops off the hangingbrake-frames, or to put the same on as required.

2. The combination with spindles and loose hanging frame-brakes adaptedto make contact therewith, of weighting-levers for such brakes,- and alifting rail or wire for said 1evers, a rocking shaft to actuate saidrail, and a chain, connected at one end to the weighting-levers, hangingloose in the form of a loop, and a shaft on which the other end of thechain may be wound or unwound, as and for the purpose described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
